UK long range weather forecast
Through the majority of this period, it will be mostly dry and settled for many areas, especially in the south of the UK. More unsettled conditions with spells of rain and strong winds may affect the north and northwest at times. These unsettled conditions could spread to other parts of the UK later in this period, but widespread unsettled conditions are unlikely. Temperatures are likely to be mostly around normal, although it may become warm for a time in the south and perhaps very warm in the southeast. Towards the end of the period, conditions may start to trend towards more generally settled weather for most areas, but with the possibility of the occasional bout of wetter weather.
Updated:
Although confidence remains low throughout this period, the preferred scenario favours a more settled regime. There should be plenty of dry, fine weather around, though there is still the risk of occasional bouts of rain and strong winds. Such spells are mostly likely across the north and west, but they could spread to other areas at times. Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived.
